He's talking to computer programmers about what skaters do. But I also found the last 2 minutes of the lecture about how much time spent practicing and how when we get something almost nailed we can easily side track ourselves and hinder our progress. I also thought a lot of the things he talks about in this lecture can easily be applied to the way we practice and play music.

I also see a lot of similarities between skateboarding and playing bass. When he talks about changing where he is focusing during a trick is to me like when you are playing a line and you are going to throw in a lick and you think about where to shift or where to put in string skips. Or you start thinking about aiming for chord toes while coming up with a bass line.
